Sub-stats — value of one roll (5★)
Every +3 levels grants one roll, landing randomly on one of the three values below. These are the true values added to your stats; the in-game panel shows them rounded down.
| Stat | Low | Mid | High |
|---|---|---|---|
| HP | 33.9 | 38.1 | 42.3 |
| ATK | 16.9 | 19.1 | 21.2 |
| DEF | 16.9 | 19.1 | 21.2 |
| HP | 3.5% | 3.9% | 4.3% |
| ATK | 3.5% | 3.9% | 4.3% |
| DEF | 4.3% | 4.9% | 5.4% |
| SPD | 2 | 2.3 | 2.6 |
| CRIT Rate | 2.6% | 2.9% | 3.2% |
| CRIT DMG | 5.2% | 5.8% | 6.5% |
| Effect Hit Rate | 3.5% | 3.9% | 4.3% |
| Effect RES | 3.5% | 3.9% | 4.3% |
| Break Effect | 5.2% | 5.8% | 6.5% |
What main stat to run, by role
| Body | Feet | Planar Sphere | Link Rope | Sub-stat priority | |
|---|---|---|---|---|---|
| Main DPS | CRIT Rate or CRIT DMG | ATK% or SPD | the character's own Elemental DMG Boost | ATK% (or Break Effect for a break-focused kit) | CRIT comes first — aim for roughly a 1:2 ratio of CRIT Rate to CRIT DMG — then ATK%, then SPD. |
| Healer | HP% or Outgoing Healing Boost | HP% | HP% | Energy Regeneration Rate or HP% | HP% first, then SPD — healing output scales off the target's Max HP. |
| Tank / Shielder | DEF% or Effect Hit Rate | DEF% or SPD | DEF% | DEF% or Energy Regeneration Rate | DEF% first, then Effect Hit Rate, then SPD. |
| Support | No safe default — depends on the character's kit, check that character's page | SPD, almost always correct | No safe default — depends on the character's kit, check that character's page | Energy Regeneration Rate | SPD first; add Effect Hit Rate if the character applies debuffs. |
This is a default framework, not a hard rule. Some characters break from it because of their own kit — for example a support that needs CRIT DMG or Break Effect instead of Energy Regeneration Rate. Always check that character's page before locking in a set.
Basic rules you need before picking Relics
- Head always rolls flat HP, Hands always roll flat ATK — no need to check the main stat on these two, just look at the substats.
- Only Feet can roll SPD as a main stat; only the Link Rope can roll Energy Regeneration Rate as a main stat.
- A substat never duplicates that piece's own main stat, and the four substats never duplicate each other.
- Each piece caps at 4 substats. Every +3 upgrade grants one roll — either unlocking a new substat line or boosting an existing one at random.
- Enhancement cap by rarity: 2-star +6, 3-star +9, 4-star +12, 5-star +15. Starting substat count: 3-star 1–2 lines, 4-star 2–3 lines, 5-star 3–4 lines.
- The main stat is NOT random — at the level cap it's always the exact same fixed number. Only substats roll randomly.
- Quick filter trick: enhance to +9 and you already see enough substat quality to decide keep-or-salvage — don't burn all your resources to +15 before judging.
Should you keep or salvage this piece?
- Wrong main stat for the slot (e.g. an HP% Sphere on a Lightning DPS) → salvage it right away, don't get attached.
- Right main stat but the 4 substats don't have even one line of CRIT Rate / CRIT DMG / SPD (for a DPS role) → low value, salvage first.
- Right main stat plus at least 2 substats you actually need from the start → enhance to +9 and reassess — this piece is worth investing in.
Where can you get Relics?
- Cavern of Corrosion — the main source of the 4 Cavern Relic pieces, with 6 difficulty tiers tied to your account's Equilibrium Level; the higher your Equilibrium Level, the thicker the 5-star drop rate.
- Simulated Universe — source of the 2 Planar Ornament pieces, only unlocked from World 3 onward.
- Divergent Universe — a second source for Planar Ornaments, separate from the Simulated Universe.
- Operation Briefing — clearing these objectives also pays out Relics and related materials.
- In-game shops — some vendors sell full 4-piece sets directly for in-game currency.
- Treasure chests scattered across the main story maps.
- Story quest rewards, plus milestone rewards for leveling up your Trailblaze Level.
Relics unlock during the Belobog story arc. To target the exact set and slot you need instead of farming blind, use the Omni-Synthesizer: it runs on Relic Remains, which you get by salvaging Relics you don't use. The machine unlocks from Equilibrium Level 3 onward.
Every piece & its lore
Firesmith's Obsidian GogglesHead
Firesmith's Obsidian GogglesProtective goggles crafted from dark-black fire crystals. Through these lenses, even the flurry of intense sparks becomes a mosaic of dull shadows.
Ever since the arrival of the liberated Firesmith Clan in the world of Warforge, their skills bloomed to the extremes while also becoming tainted with the aura of Destruction.
The dazzling light of the furnace, the sparks of metal clashing, and the long-lasting forging process can turn raw ore into a fine weapon, but can also gradually strip the firesmith of their eyesight. One day, at the bottom of a volcano, Foy found a deposit of rare obsidian flame crystal. From this, he carefully polished a pair of protective goggles, which transformed the fierce sparks of fire into pale-white silhouettes. However, the greedy smith was unable to fully escape his cursed fate either, burning everything he was into cinders in the ultimate fire.
Foy deemed the Antimatter Legion in the Warforge as the raw materials for his creations, and himself as the rising flame.
"I wonder... is it possible to harness the power of a thermonuclear reaction in my furnace?" Foy's pursuit of the ultimate fire came to an unfruitful end in an out-of-control thermonuclear fusion.
Firesmith's Ring of Flame-MasteryHands
Firesmith's Ring of Flame-MasteryA ring with a symbol of flames. It is the highest symbol of honor among the Firesmith clan.
Creatures of the Legion crave for separation from the material existence, longing for the fundamental mutations that can only be brought forth by the scorching heat waves of Destruction.
A highly-skilled master Firesmith can raise the forge's temperature to unbelievable levels — the flame's black-body radiation would exhibit the blue spectrum like that of a dying star. Firesmiths are also geniuses at controlling flames, but only the best among them are bestowed with a ring of flame-mastery as a mark of their superb skill.
The Warforge had long ceased to differentiate between the smith and the smithed. All those Firesmith masters who had been smelting the Antimatter Creatures had also become parts of the Weapons of Destruction.
"The smelting depends on the temperature, and the temperature depends on the Firesmith." This is matter-of-fact knowledge to any Firesmith who can control the art of Destruction.
Firesmith's Fireproof ApronBody
Firesmith's Fireproof ApronA blacksmith's apron without any superfluous adornment. The texture of the leather and the family emblem are clearly visible.
In this scorching world of lava, as long as the smelting and hammering never ceased, creation and destruction were no longer polar opposites of each other.
Surtur was especially good at using the molten magma that erupted from active volcanoes to infuse the Legion's creatures with a violent aura of destruction. Neither the bubbling of toxic gases nor the gurgling of magma could interrupt Surtur's concentration at the forge. Though burning waves of molten rock would splash on Surtur's fireproof apron of giant firelizard skin, the leather never lost its luster when the flames faded.
A massive proportion of the Legion's fighting forces were repeatedly hammered and smelted in the forge until their flesh and weaponry were fused together under the hammers of the Firesmiths, becoming weapons of Destruction.
"This incomparable power of destruction..." The Firesmiths who control the flames have never hidden the terrible aspirations they place in their weapons.
Firesmith's Alloy LegFeet
Firesmith's Alloy LegA prosthetic produced from metallic alloy. Its surface is entwined with vivid fiery carvings.
It was the Master of Destruction that set free the imprisoned Firesmith clan and bestowed upon them the mark of Destruction which in turn granted the Firesmiths unlimited power.
Despite the inability to move around like an able-bodied man, the chief of Firesmith obtained true freedom, for he was no longer imprisoned just for his extraordinary skills and talents in the art of Firesmithing. The chief poured in all his resentment and humiliation into the forge and would never be tired, not even by days of non-stop hammering. Upon one hammering after another, the once stubborn and proud antimatter creatures had to eventually change their form and give in to the remolding by the Destroyer.
Despite being free from any tangible cages, the Firesmiths' obsession with forging had become another form of prison for them, had it not?
"Flesh and blood are a burden. Forging is also destruction." The chief looked at the ever-growing number of deformed Firesmiths and lamented.

How to read this relic set page
Cavern Relics have 4 pieces: Head and Hand always carry fixed flat stats (HP and ATK), so only Body and Feet have a random main-stat you actually choose. The 2-piece effect unlocks with 2 out of 4 pieces from the same set; the 4-piece effect is stronger but needs all 4 and usually has its own trigger condition — read the exact text above before committing. Planar Ornaments only have 2 pieces (Planar Sphere + Link Rope) and only ever have one 2-piece effect, there is no 4-piece version.
The two types also differ in where you get them: Cavern Relics drop from the Cavern of Corrosion and cost Trailblaze Power per run; Planar Ornaments come from the Simulated Universe or Divergent Universe, which do NOT cost Trailblaze Power — you trade for them with items or completion rewards instead. A full loadout usually combines one 4-piece Cavern set (or two different Cavern sets at 2 pieces each) with one 2-piece Planar set — go 4-piece when that set gives a large, reliable damage buff, and mix 2+2 when you need to stack several smaller stats (e.g. ATK% from one set plus Elemental DMG% from another).
The "who should use this" list is pulled from cross-sourced build consensus and updates automatically as the meta shifts, it is not hand-picked. See the full set table on the Relics page, or check terms in the HSR Glossary.
